Andrew Smith Posted January 2, 2013 Report Share Posted January 2, 2013 If anyone wants to do the conversion I can give you the part numbers etc soy oil gesture to get the right callipers! Steve Steve, You have a PM. Cheers Andrew Quote Link to post Share on other sites
whatmore179 Posted January 3, 2013 Report Share Posted January 3, 2013 Hi Steve Do you know if your conversion fits the Tr steel wheel? Steve Quote Link to post Share on other sites
Steves_TR6 Posted January 3, 2013 Report Share Posted January 3, 2013 Hi SteveDo you know if your conversion fits the Tr steel wheel? Steve Hi Steve My understanding is it does, but I can't be sure. It's not my idea, I nicked it from the Vintage Triumph Register in the us, I think John Lye did most of the investigation. Have a look at http://www.vtr.org/maintain/brake-conversion.shtml Regards Steve Quote Link to post Share on other sites
mike3md Posted January 3, 2013 Report Share Posted January 3, 2013 Hi Steve, If the extra pedal travel is a problem, even with the air out of the system, you could try a larger diameter master cylinder. The extra effort will be minimal, especially with the servo. Mike Quote Link to post Share on other sites

Any idea if there is a suitable 'larger bore' MC available that would bolt to the std servo? Thanks Steve Edited January 3, 2013 by SDerbyshire Quote Link to post Share on other sites

Guest ntc Posted January 3, 2013 Report Share Posted January 3, 2013 If you measure the contact area of the pistons it may surprise you and then add on the amount of fluid required to feed them Quote Link to post Share on other sites
Steves_TR6 Posted January 3, 2013 Report Share Posted January 3, 2013 Anybody know the diameter of the standard MC? I've fond a couple of potential replacements from land rovers...... Quote Link to post Share on other sites

Steves_TR6 Posted January 3, 2013 Report Share Posted January 3, 2013 I'll answer my own question, std seems to be 13/16, which I make to be 21mm. The Landrover ones equate to 7/8 or 1" Interesting! I think ill investigate these further at the weekend, unless someone else has the time ...... I guess we need to know if their mountings are the same, and the servo side fitting. I'm betting they are the same...... Steve Quote Link to post Share on other sites
Guest ntc Posted January 3, 2013 Report Share Posted January 3, 2013 Steve I was referring to the calipers Quote Link to post Share on other sites
Steves_TR6 Posted January 4, 2013 Report Share Posted January 4, 2013 SteveI was referring to the calipers Yep, bigger callipers with bigger piston area= longer pedal travel. The suggestion is to up the master cylinder bore size to compensate. I believe std bore is 13/16, the land rover ones are 7/8 or 1" Stuart and Neil, do you think this is worth investigating?

Grabea Posted January 4, 2013 Report Share Posted January 4, 2013 Excellent links Stuart, I was already thinking that the larger master cylinder, whilst it will reduce pedal travel, would increase the effort required at the pedal, your links confirmed my thoughts.

Steves_TR6 Posted January 6, 2013 Report Share Posted January 6, 2013 So after much searching I've come to the conclusion that the girling MC of a series 2 land rover might be suitable. The swb land rover has a 22mm bore MC, the lwb a 25.4 mm one ( ie 1 inch) These both come in two styles, where the reservoir is held on with either roll pins, or in the style of the TR6 one with a couple of screws. Being as they are cheap I've ordered the 1" one with the TR6 style screw fitting. It will be interesting when it arrives to compare with the standard one, I'm guessing Girling made a range of cylinders in various bore sizes, and that they are all fundamentally compatible....... Time will tell ! It may be a couple of weeks before I can get around to experimenting further, as am in Edinburgh next weekend, but if the cylinder comes this week I'll at least line them up for photos.

Jersey Royal Posted January 6, 2013 Report Share Posted January 6, 2013 (edited) Good Luck Steve Am interested in your results I did once change my gearbox slave cylider to the next size up whatever that was, the extra force required was suprising , much heavier. leg was aching after use, put it back as it was, what relief Cheers Guy Edited January 6, 2013 by Jersey Royal Quote Link to post Share on other sites
Steves_TR6 Posted January 6, 2013 Report Share Posted January 6, 2013 Yes Guy, I expect that may be the case here! Presently the pedal is very light, and I may also increase the size of the rear cylinders. If the 1" gives too heavy a pedal there's always the 7/8 " to try :-) Quote Link to post Share on other sites
mike3md Posted January 7, 2013 Report Share Posted January 7, 2013 You could always also change the servo for one with a higher ratio........... :-) Mike Quote Link to post Share on other sites

Denis Posted January 7, 2013 Report Share Posted January 7, 2013 (edited) In a word Brake...'Earlier'! The huge improvement in modern cars brakes and tyres, means I just plan my braking in my TR much earlier than I used to have to! I remember in the early 1970's, I only had to worry about XJ6's and the very occasional Lotus...it's silly to expect to run in a train of modern traffic today and expect a 40 year old car to be on par with them!

Steves_TR6 Posted January 9, 2013 Report Share Posted January 9, 2013 Update the LR MC arrived today, excellent service from the DLS landrover specialists. At first glance it looks promising, outlets are the right sized and in the right sort of layout, but the reservoir will likely be too high for the TR bonnet........ Hopefully will be able to line it up tomorrow and take some photos, but test fitting will be a week or two as were off to Edinburgh this weekend. Watch this space !

Steves_TR6 Posted January 10, 2013 Report Share Posted January 10, 2013 OK, i couldn't resist having a look at the new MC today as was out putting the rocker cover back on complete with new O ring seal from Racetorations, thanks to Darryl for the speedy service ! It bolts right up to the servo, the outluet pipes are the same sizes and same location, the only fly in the ointment looks like being the height of the reserviour, which will likely foul the bonnet I don't have the time today to complete a test fit, with bleeding etc, so you'll have to wait for a full verdict but here's some photos from today : Quote Link to post Share on other sites
